Euclid Q1 reveals spatial variations of the extinction law in the dense cloud LDN 1641
Rui Chen, Shu Wang, Xiaodian Chen +1
Dust extinction laws are essential for precision photometry and provide a direct probe of grain properties, but their behaviour in dense molecular clouds remains poorly constrained…
Dimensional structure of thermodynamic topology in ultraspinning Kerr-AdS black holes
Min Tian, Ying Chen, Di Wu
In this paper, we apply the thermodynamic topology framework to ultraspinning Kerr-AdS black holes in arbitrary spacetime dimensions. By constructing the off-shell Helmholtz free e…
Entanglement dynamics for atoms near a reflecting boundary: Enhancement and suppression by environment-induced interactions
Ying Chen, Hongwei Yu, Jiawei Hu
We investigate how environment-induced interactions influence the entanglement dynamics of two atoms held at fixed positions near a perfectly reflecting boundary. Within the framew…
Strong field gravitational lensing of particles by a black-bounce-Schwarzschild black hole
Guansheng He, Jiaxu Huang, Zhongwen Feng +2
The gravitational lensing of relativistic and nonrelativistic neutral massive particles in the black-bounce-Schwarzschild black hole spacetime is investigated in the strong deflect…
